Hi @snowymo, thanks for your patience whilst we investigated this issue. So long as the code is unaltered as you said, it should be able to run without any issue.
As you mentioned, the Unity SDK is working fine, how about the c# sample for the interaction library? What exactly is the output you receive from the c++ code?
Regarding the licence, if you are developing only a game for interaction purposes then no special action is required, but you mentioned you wish to track for a web page which is now being used for analysis which changes the situation.. could you kindly clarify more precisely the project intentions? Many thanks
